Storage Area Networks (SANs) and Software-Defined Networking (SDN) Quiz

SAN stands for Storage Area Network, a network that provides access to consolidated, block-level data storage.

SAN primarily serves for efficient data storage and retrieval across interconnected servers and storage devices.

SDN aims to centralize network control to allow for more efficient management and optimization of network resources.

SDN primarily operates at the Network Layer (Layer 3) of the OSI model, focusing on routing and forwarding decisions.

Storage Virtualization enables the abstraction of physical storage resources, allowing for more efficient management and utilization in a SAN.

The Control Plane in SDN is responsible for making decisions about how to manage traffic based on network policies and objectives.

Traditional networks typically have centralized control, while SDN introduces decentralized control for better adaptability and scalability.

FCoE, or Fibre Channel over Ethernet, is commonly used in SAN environments for efficient communication between servers and storage devices.

The main advantage of FCoE in SAN environments is lower latency, enhancing data transfer speed and responsiveness.

A potential drawback of SDN implementation is the complexity in management, requiring skilled personnel and careful planning.

SDS systems offer agility and flexibility in managing and provisioning storage resources, adapting to changing demands and workloads.

iSCSI offers a lower cost alternative to Fibre Channel for SAN connectivity, utilizing existing Ethernet infrastructure.
